Outputs are five SPDT relays — two Form C and three Form C — each rated 3A at 200VAC. That gives you independent control for pump start/stop, high-level alarm, low-level alarm, and a spare for a remote indicator or valve. The control-to-sensor distance is rated up to 1 km, which covers remote tank farms or elevated reservoirs where the controller sits in the main panel and the electrodes are field-wired out to the tank.
The package is bulk, so it ships individually for one-off replacements or in quantity for panel builds.
